摘要： The invention relates to a method and devices for enabling a user to visualise a virtual model in a real environment. According to the invention, a 2D representation of a 3D virtual object is inserted, in real-time, into the video flows of a camera aimed at a real environment in order to form an enriched video flow. A plurality of cameras generating a plurality of video flows can be simultaneously used to visualise the virtual object in the real environment according to different angles of view. A particular video flow is used to dynamically generate the effects of the real environment on the virtual model. The virtual model can be, for example, a digital copy or virtual enrichments of a real copy. A virtual 2D object, for example the representation of a real person, can be inserted into the enriched video flow.

摘要： The invention relates to a method for determining the arrangement of a video capturing means in the capture mark of at least one virtual object in three dimensions, said at least one virtual object being a modelling corresponding to at least one real object present in images of the video image flows. The inventive method is characterised in that it comprises the following steps: a video image flow is received from the video capturing means; the video image flow received and at least one virtual object flow are displayed; points of said at least one virtual object are paired up, in real-time, with corresponding points in the at least one real object present in images of the video image flows; and the arrangement of said video capturing means is determined according to the points of the at least one virtual object and the paired point thereof in the at least one real object present in the images of the video image flows.

摘要： The invention concerns a method and a system for: (i) producing in a computer processing unit a flow of synthetic images, and (ii) tracing a scene by creating visual interactions between the synthetic image flow and at least one video image flow. The computer processing unit comprises: a motherboard, a graphics board for scene rendering and display, including a processor for accelerating 2D/3D processing, a work buffer and a texture memory, an acquisition means for acquiring in real time video images, in a video buffer. The specific rendering of the scene is carried out: by recopying the video buffer in a memory zone of the graphics board, by tracing the synthetic images in the work buffer.
